Effect of parenteral nutrition on protein synthesis in adult cancer patients.
The rate of whole body protein synthesis was measured with 15N glycine in three groups of subjects: 1) normal healthy adult controls, 2) semistarved adult patients with upper gastrointestinal tract malignancies and, 3) a group of patients similar to 2) except they were maintained parenterally on a regimen adequate in amino acids and glucose. By comparing the patient results with data obtained from rat studies with 15N glycine were concluded that the patients were protein rather than energy depleted.
